Answer:
A
Explanation:
Because the Bohr model explains the Conteplation of the Atom which consedes to the answer explaing the neutrons and electrons have a relation which makes A right.
The Moon<span> moves </span>around<span> the </span>Earth in<span> an </span>approximately<span> circular </span>orbit<span>, going once </span>around<span> </span>in approximately<span> 27.3 </span><span>days. </span>The moon orbits quite fast: it moves about 0.5 degrees<span> per hour in the sky. So, its average movement in a day is around 13 degrees. 5 days x 13 degrees is approximately 65 degrees. </span>
The question is incomplete. The complete question is:
In an experiment similar to the one described in this procedure, a saturated solution of Mg(OH)2 was titrated with 0.0500 M HCI solution. The equivalence point was reached when 0.330 mL of the acid had been added to 50.00 mL of the saturated Mg(OH)2 1. How many moles of H+ were added? How many moles of OH were present in the initial solution of magnesium hydroxide? 2. What are the concentrations of OH and Mg2 in the original 50.00 mL solution? 3 Write the equation for dissolving Mg(OH)2 in water 4. Write the corresponding Ksp expression. 5. What is the value of Ksp found from the experimental data above?
Answer:
Ksp=5.4×10-8
Explanation:
We must find find the concentration of base from the information provided. Then we can now find the concentration of hydrogen ions in the acid, concentration of magnesium ions and hydroxide ions in the base and finally the solubility product of the magnesium hydroxide solution as required. See image attached for more details of the solution to the problem.
For an ideal gas, the ideal gas equation can be used to relate the changes in the conditions of the system. The equation is expressed as:
PV = nRT
Therefore, the following are classified as:
P and T = directly proportional
V and n = directly proportional
T and V = <span>directly proportional</span>
P and V = inversely proportional
P and n = directly proportional
